Appraisal
Structural: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Deck Geometry: Basically intolerable requiring high priority of replacement [2]
Road Alignment: Basically intolerable requiring high priority of corrrective action [3]
Waterway: Superior to present desirable criteria [9] and Bridge foundations determined to be stable for assessed or calculated scour condition. [5]

Future Work
Work Needed: Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
